BELT-BUCKLE.

Application filed. July 22, 1921.

T 0 all whom it may concern:

Be it known that I, ERNEST N. HUM- PHREY, a citizen of the United Statesof America, residing at New Britain, Connecticut, have invented a newand useful Belt- Buckle, of which the following is a specification.

My invention relates to buckles of a type particularly useful inconnection with belts. The object is to simplify and cheapen theconstruction without sacrifice to quality or efliciency.

In the drawings:

Figure 1 is a perspective view of a buckle in position to receive thefree end of a belt;

Fig. 2 is a sectional View showing the gripping member in position topermit adjustment of the belt; r

Fig. 3 is a view similar to Fig. 2, showing the gripping member grippingthe belt, and

Fig. 4 is a perspective view showing parts of the buckle relativelyseparated.

1 represents a front plate having rearwardly extending flanges 2-2 atthe upper and lower edges forming a belt passage between them. 3represents a plate pivotally connected at 44l near the rear edges of theflanges 22 and intermediate the ends of the same. At the outer end ofthe plate 3 is pivotally connected another plate 5. This last mentionedplate 5 has belt'gripping teeth 66 which coact with the body of theplate 5 in fixedly securing one end of the belt to saidlever. The otherend of'the plate 5 is provided with an offset portion 7 which, when thelever is pinched down on the fixed end of the belt, stands close to thepivotal portion 4 of the plate 3 so as to form in effect a cam, whichcam operates to pinch the adjustable end of the belt tightly against theback of the plate 1 when the belt and buckle are in operative positionas shown in Fig. 3. Manifestly, a strain on the fixed end of'the belttends to hold. the cam 7in position against any possible accidentaldisplacement. By this very simple arrangement of parts, the same maybe'very quickly made and assembled. 8 representsa belt. 99 are earswhich may be provided at each side edge of plate 3 for engaging the sideedges of the fixed end of the belt.

' plate 3, the degree to which the cam is offset from the pivotalmounting of said plate 3 may be varied to adapt the sameto belts ofdifferent thickness.

I claim 1. In a buckle, a front plate having rear I wardly extendingflanges at the upper and lower edge, a plate pivotally connected between said flanges, another plate pivotally connected to the free end ofthe first plate and coacting therewith to grip one end of a belt, a camnear the free end of the last mentioned plate, said camlying adjacent tothe pivotal portion of the first mentioned plate when the parts areassembled with a belt whereby said cam will operate to grip theadjustable end of a belt between it and the back of a front plate.

2. In a buckle, a front plate having rearwardly extending flanges at theupper and lower edge, a plate pivotally connected be tween said flanges,another plate pivotally connected to the free end of the first plate andcoacting therewith to grip one end of a belt, a cam near the free end ofthe last mentioned plate, said cam lying adjacent to the pivotal portionof the first mentioned plate when the parts are assembled with a beltwhereby said cam will operate to grip the adjustable end of a beltbetween it and the back of a front plate, ears at the edges of the firstmentioned plate arranged to engage the adjacent side edges of a beltresting thereon.

3. In a belt buckle, a front plate, a rearwardly extending flange at theupper and lower edges thereof, a member pivotally con nected at one endbetween said flanges, another member pivotally connected at one end tothefree end of the first mentioned member. the last mentioned memberhaving an offset at its free end arranged to lie adjacent to the pivotalpart of the first mentioned member when said members are folded togetherwhereby said offset will function as 'a cam and cooperate with the frontplate in holding the adjustable end of a strap belt in place.
